The increasing importance of sustainability in energy production has led to a global commitment to the use of fuels derived from renewable biological sources, such as biodiesel produced from plant crops or biomass residues, that do not compete with human food for their production. For a biofuel to be considered biodiesel, it must satisfy the specifications described in the UNE 14214, with the UNE‐EN 14103 referring to the determination of fatty acid methyl ester content. This standard applies gas chromatography as an analytical technique. Gas chromatography is a widely used technique in the analysis of methyl ester although it has a number of drawbacks such as: long analysis times, a high consumption of high‐quality gases and internal standards, does not allow the analysis of different compounds with the same column, etc. From an industrial production point of view, is necessary to know the fatty acid methyl ester content in biodiesel samples quickly. This paper studies the development of an analytical method using Fourier transform infrared spectroscopy (FTIR) as alternative to gas chromatography (GC), since it is a simple, rapid, and precise analytical technique to quantify fatty acid methyl ester content in biofuel samples.

傅里叶变换红外光谱法分析生物柴油中脂肪酸甲酯的含量：方法与气相色谱法比较

可持续发展在能源生产中的重要性日益提高，已导致全球对使用可再生生物来源的燃料做出承诺，这些可再生生物来源例如是植物作物产生的生物柴油或生物质残渣，不会与人类食品竞争生产。对于要被视为生物柴油的生物燃料，它必须满足UNE 14214中描述的规格，UNE-EN 14103是指脂肪酸甲酯含量的测定。本标准适用于气相色谱分析技术。气相色谱法是分析甲酯的一种广泛使用的技术，尽管它具有许多缺点，例如：分析时间长，高质量气体和内标物的消耗量大，无法对具有相同成分的不同化合物进行分析专栏等 从工业生产的角度来看，有必要快速了解生物柴油样品中的脂肪酸甲酯含量。本文研究了一种使用傅里叶变换红外光谱（FTIR）替代气相色谱（GC）的分析方法的发展，因为它是一种定量生物燃料样品中脂肪酸甲酯含量的简单，快速且精确的分析技术。
